Bcrypt API for Scala.js

bcrypt - A bcrypt library for NodeJS.

Description

bcrypt is a password hashing function designed by Niels Provos and David Mazières, based on the Blowfish cipher, and presented at USENIX in 1999.

Build Dependencies

• SBT v1.2.x

Build/publish the SDK locally

 $ sbt clean publish-local

Running the tests

Before running the tests the first time, you must ensure the npm packages are installed:

$ npm install

Then you can run the tests:

$ sbt test

Examples

Using Bcrypt asynchronously via callbacks

import io.scalajs.npm.bcrypt._

val saltRounds = 13
val myPlaintextPassword = "b@c0n"

Bcrypt.hash(myPlaintextPassword, saltRounds, (_, hash) => {
    Bcrypt.compare(myPlaintextPassword, hash, (_, isMatch) => {
      println(s"The password was a match: $isMatch") // The password was a match: true
    })
})

Using Bcrypt asynchronously via promises

import io.scalajs.npm.bcrypt._

val saltRounds = 13
val myPlaintextPassword = "b@c0n"

for {
    hash <- Bcrypt.hash(myPlaintextPassword, saltRounds)
    isMatch <- Bcrypt.compare(myPlaintextPassword, hash)
} {
  println(s"The password was a match: $isMatch") // The password was a match: true
}

Using Bcrypt synchronously

import io.scalajs.npm.bcrypt._

val saltRounds = 13
val myPlaintextPassword = "b@c0n"

val hash = Bcrypt.hashSync(myPlaintextPassword, saltRounds)
val isMatch = Bcrypt.compareSync(myPlaintextPassword, hash)
println(s"The password was a match: $isMatch") // The password was a match: true

Artifacts and Resolvers

To add the Bcrypt binding to your project, add the following to your build.sbt:

libraryDependencies += "io.scalajs.npm" %%% "bcrypt" % "0.5.0"

Optionally, you may add the Sonatype Repository resolver:

resolvers += Resolver.sonatypeRepo("releases")
